A man who eluded officers for about 15 hours after allegedly shooting four relatives to death surrendered Friday on a rocky ridge on a remote Indian reservation.

Stanley Secatero, 25, killed his relatives Thursday night, authorities said. He apparently was upset because he believed they had turned his brother in to police for a $1,000 reward.Secatero had fled into the rugged sandstone formations of the remote Canoncito Navajo Reservation 30 miles west of Albuquerque.

He surrendered only a few minutes after a police negotiator began talking to him as he stood sobbing on the ridge, a .22-caliber rifle in his hand, Navajo police said. He dropped his rifle before surrendering.

Police converged on the ridge after getting a call from a resident who was using binoculars and spotted an armed man. Some 80 federal, tribal and local law enforcement agents worked to track down Secatero.

A Navajo investigator had said earlier in the day that two additional people were killed. FBI Agent Ron Dick said he could confirm only five victims - four dead and one wounded. Navajo police referred all questions to the FBI.

"This is a very sudden shock," said Tony Secatero, president of the Canoncito Navajos. About 2,800 people live in the rural community. Tony Secatero is not related to Stanley.

Stanley Secatero is accused of killing his grandmother, two aunts and an uncle and wounding one other person.

The dispute apparently involved Secatero's 33-year-old brother Wesley, who was jailed on an aggravated battery charge in Albuquerque. Secatero believed other family members had turned his brother in for a reward, said Brenda Platero, who lives a half-mile from the shooting scene.

Secatero was taken to Albuquerque, where he was arraigned Friday evening before U.S. Magistrate Don Svet on an outstanding assault warrant from 1994.

Platero's boyfriend, Raymond Willis, said he saw the bodies of Secatero's aunt and uncle, Agnes and Eddie Secatero, lying in the mud beside their truck. The other dead were identified by neighbors as Secatero's grandmother, Lena Secatero, and his aunt, Rose Nelson.
